His first treatise covers recorder playing: Opera intitulata Fontegara (Venice, 1535). His second (in two volumes) is about the viola da gamba: Regola Rubertina (Venice, 1542) and Lettione Seconda (Venice, 1543). They cover both technicalities of playing and the subtleties of expression. There is also guidance on ornamentation—passaggi.
